Yes, I have the same problem, I traced it to some body parts inside my
head (YMMV). I have a fairly large hole in my hearing spectrum that
extends from about 700 Hz to light. In fact most everything from 350 Hz
down to DC is also pretty punk. Last audiology exam the VA gave me
showed a small but good looking peak in my organix response around 650
Hz, which is where I put my K2 sidetone. As luck would have it, that is
close to the TS-850 sidetone as well, although it is seeing less and
less use now that I have the K2/100.
Seriously, I tried out your observation on my K2 with the QRP top on,
and my wife tells me it got distinctly weaker around 600 Hz ... I can't
really tell. I tried stuffing the enclosure full of cotton balls (I
said "seriously," I really did do this), and it softened the character
of the "hole." I guess I'd expect cotton to soften. She couldn't hear
any real "hole" using the KPA100 speaker, but did say it didn't sound
quite as nice ... whatever that means to the audio engineers.
Since I use amplified headphones with the AF gain all the way up, the
speaker hole doesn't bother me. Neither does the not-so-nice-sounding
KPA100 speaker. Again, YMMV.
NEW SUBJ: I finally figured out what to do to TR-Log to get it to talk
to the K2 (it involved reading the TR book, and then realizing I needed
to also turn the K2 serial port on in the menu ... I just love to solve
these really technical electronics problems), and I fear the TS-850 is
going get lonelier in contests now.
I'm still amazed by my radio, and, while I didn't design it, I did build it!
